Check out what the 16-year-old Kick-Ass 2 actress and her 23-year-old co-star had to share:

Christopher, on having fun with Chloe during press tours: “In almost every interview, Chloë would beat me up. She was in fight training for months, and she was really freaking strong. All we would do was sing [Lady Gaga's] ‘Paparazzi,’ The beautiful harmony of that chorus.”

Chloe, on their next song they can belt out together: “I found a new song for us: ‘Come & Get It’ by Selena Gomez. It’s easy to learn. We can kill it.”
